Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes

New Phytologist, EarlyView.
Kinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...

Biotransformation of monoterpenols upon pre‐treatment with oregano essential oil vapour alleviates downy mildew susceptibility in grapevine leaves

Plant Biology, EarlyView.
Pre‐treatment of grapevine plants with oregano essential oil vapour alleviates downy mildew susceptibility by accumulation of monoterpenol glycosides. Abstract Grapevine downy mildew, caused by the oomycete Plasmopara viticola, is a destructive disease that causes major economic losses as most elite grapevine cultivars are susceptible to this pathogen.

Early evolutionary history of the seed

Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Transcellular Ion Currents during Sporangium Development in the Water Mould Achlya bisexualis [PDF]

Microbiology, 1988
Changes in the pattern of electric currents that accompany the transformation of growing hyphae of Achlya bisexualis into sporangia have been examined. When hyphae were transferred to a non-nutrient buffer, they continued to extend for several hours and then gave rise to sporangia.

Exploring the Antifungal Potential of the Brown Macroalga Hormophysa triquetra: Morphological Disruptions and Structural Changes in Plant Pathogens

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Extracts of Hormophysa triquetra showed antifungal activity with marked hyphal deformities in Fusarium oxysporum and Alternaria alternata. Light microscopy and SEM confirmed structural alterations despite unchanged radial growth. Cucumber assays validated reduced disease incidence, linked to fatty‐acid–rich metabolites detected by GC–MS.

Airborne Plasmopara viticola Sporangia: A Study of Vineyards in Two Bioclimatic Regions of Northwestern Spain

Horticulturae
Downy mildew, caused by Plasmopara viticola, is one of the most destructive diseases affecting grapevines, particularly in areas with bioclimatic conditions that favor its development, such as northwestern Spain.

Analysis of plant and environmental samples for the quarantine fungus Phyllosticta citricarpa in four European citrus‐growing areas

Annals of Applied Biology, Volume 188, Issue 3, Page 996-1012, May 2026.
Methodologies for the early detection of Phyllosticta citricarpa in air and rainwater samples were developed and applied over three consecutive years (2018–2021) in four European citrus sites, previously reported to harbour the pathogen. Phyllosticta citricarpa was not detected in plant, air, or rainwater samples, and no CBS symptoms were observed on ...

Assessing the Apparent Prevalence, Pathology and Molecular Detection of Aphanomyces invadans in Native Fish Species of the Sylhet Region, Bangladesh

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT The primary objective of this study was to investigate the presence of Aphanomyces invadans and its association with Aeromonas hydrophila in naturally infected fish from two wetlands (beels) in the Sylhet, Bangladesh. Over a 6‐month period (October 2020 to March 2021), a total of 396 fish were examined from Singari beel, of which 90 were found
